Abstract

1476910 Switching circuits INTERNATIONAL STANDARD ELECTRIC CORP 15 April 1975 [22 April 1974] 15426/75 Heading H3T A circuit for compensating for the resistance of a switch RON2, e.g. in telephone exchange equipment, comprises a controllable negative resistance - R connected in series with the switch and with a parallel network comprising a capacitor C shunted by a series connected resistor RM and D.C. source G. The voltage across the parallel network is measured by a differential amplifier KR to provide a control signal for the negative resistance to adjust it to compensate for the switch resistance.
